Human Evaluation of “Colored” Hydrogen Transactions Towards Carbon Neutrality

Abstract

An incorporated analysis of selling green hydrogen and gray hydrogen, as opposed to sellingtheir mixed hydrogen, is investigated. Specifically, we analyze how the social surplus is characterized for the mixed hydrogen. We perform supply/demand analysis of the mixed hydrogen in terms of the ratio of the green hydrogen. Furthermore, we derive the equilibrium price and social surplus, and clarify the optimal sales of green hydrogen. In addition, for the case where green hydrogen and gray hydrogen are traded in separate markets, we discuss what measures can be taken to increase the demand for green hydrogen.
